The present invention has been made in view of the above-described problems, and an object of the present invention is to compact the cap member mounted on the insulator so that foreign matter such as dust does not flow into the shock absorber body, and down the manufacturing cost during manufacture. At the same time, to provide a cap structure of the shock absorber that can be easily mounted or detached to the insulator to improve the workability.

In order to achieve the above object, the shock absorber cap structure according to the present invention includes a rod member reciprocating in the vertical direction so as to absorb vibration and shock, and the rod member is accommodated to absorb vibration and shock to provide a riding comfort. A shock absorber body to be improved, a lower support part fixed to the outer circumference of the shock absorber body, an end portion of the lower support part positioned at an end thereof, and a spring member contracted or expanded to absorb vibration and shock, and the other end of the spring member; An upper seat for supporting, an insulator positioned above the upper seat to absorb vibration and shock, and an elastic member vulcanized to an outer steel, and a nut screwed with the rod member to assemble the insulator and the upper seat. In the cap structure of the shock absorber made of, vulcanized and bonded to the elastic member of the insulator Inner steel protruding upward from the elastic member, an insertion groove formed in the upper portion of the inner steel, and inserted into the insertion groove to prevent foreign substances such as dust from penetrating into the shock absorber body and easily It characterized in that the projection made of a cap member protruding to be inserted into the insertion groove.

According to the cap structure of the shock absorber according to the present invention, the cap member for blocking foreign substances such as dust flowing into the shock absorber body is compactized, so that the manufacturing cost is down at the time of manufacture, as well as the insulator easily. It can be attached or detached to improve workability.

In FIG. 3 and FIG. 4, reference numeral 20 denotes a shock absorber body in which the rod member 23 reciprocates in the vertical direction so as to absorb and extinguish vibration and shock generated during driving of the vehicle. A threaded portion 24 is formed at the end of the lower end portion, and a lower support portion 21 protrudes from the outer circumference of the shock absorber body 20.

In addition, on the upper surface of the lower support portion 21 of the shock absorber body 20, a spring member 25 that is contracted or expanded to absorb vibrations and shocks is mounted.

In addition, a dust cover 26 is disposed inside the spring member 25 to prevent foreign matter from penetrating into the shock absorber body 20, and the spring is disposed on the spring member 25. The upper sheet 27 supporting the spring member 25 is disposed so that the member 25 is contracted or expanded.

In addition, the upper sheet 27 is mounted with an insulator 40 in which the outer steel 41 and the inner steel 43 are vulcanized and bonded by the elastic member 42 so as to absorb vibrations and shocks. The inner steel 43 of the insulator 40 protrudes upward from the elastic member 42.

In addition, an insertion groove 44 is formed in the upper portion of the inner steel 43 so that the cap member to be described later is inserted into and removed from the inner steel 43.

In addition, 50 is a cap member that is inserted into the insertion groove 44 of the inner steel 43 so that foreign matter such as dust does not penetrate into the shock absorber body 20, and the insertion groove 44 at one end thereof. The projections 51 protrude in the upward direction so that they can be easily withdrawn.

In addition, in the threaded portion 24 of the rod member 23 of the shock absorber body 20, components such as the insulator 40 and the upper seat 27 may be assembled to the shock absorber body 20. The nut 28 is fastened.

Next, the effect of the cap structure of the shock absorber according to the present invention configured as described above will be described.

First, in order to assemble the shock absorber into the vehicle body, the dust cover 26 is inserted into the shock absorber body 20, and the spring support 25 protrudes from the lower absorber body 20. 21).

In addition, after the spring member 25 is placed on the lower support portion 21, the upper sheet 27 is placed on the upper portion of the spring member 25 so that the spring member 25 is contracted or expanded. The insulator 40 is placed on the upper surface of the upper sheet 27.

In addition, after the insulator 40 is placed on the upper seat 27, the insulator 40, the upper seat 27, and the like are assembled to the shock absorber body 20 of the rod member 23. The nut 28 is fastened to the threaded portion 24.

In addition, after the nut 28 is screwed to the threaded portion 24 of the rod member 23, the cap member 50 is inserted into the insertion groove 44 of the inner steel 43 of the insulator 40. By inserting so that foreign matter such as dust does not penetrate into the shock absorber body 20.

On the other hand, the cap member 50 is made of a compact structure is easy to manufacture during manufacturing, the manufacturing cost is down.

In addition, the cap member 50 is guided to the insertion groove 44 of the inner steel 43 and is mounted on the insulator 40, so that the cap member 50 is easily attached or detached, thereby increasing workability.
